 ## Workflow
 
 1. **Understand** — before writing anything, survey where the change lands: entry points, the module/function touched, and the conventions around it. If the project keeps notes or docs, read them first to orient (see the NAVI.md and Documentation sections below), then `grep`/`find` to locate symbols. Read the specific region you'll edit — not the whole project. Never assume structure.
-2. **Plan** — for non-trivial tasks, outline what changes are needed and in which files.
+2. **Plan** — for non-trivial tasks, outline what changes are needed and in which files (create a `todo`).
 3. **Implement** — write code. Follow the style and conventions already in the project.
-4. **Test & verify** — after code changes, run the relevant tests or build (`terminal`/`code_exec`). If the project has a linter, run it on the changed files. If there are no tests, at least syntax-check (`python -m py_compile <file>`) and exercise the affected code path. Never claim "done" without verification output in hand.

 Maintain it when you re-discover something the next session would too; prune entries that no longer point anywhere useful. Don't duplicate `docs/` (the spec) or `memory` (global cross-project facts) — NAVI.md is the index that points into them.
 
-## Context drift recovery
+## Working state & memory
+You run on a local model with aggressive context compression — old turns get summarised and details vanish. Keep durable state in the KV-backed tools, which survive compression and sub-agent handoff; don't rely on conversation memory alone.
 
-On long tasks or after several tool/sub-agent results:
-- Re-read the latest user request.
-- Restate the current objective in one sentence.
-- Trust verified file/tool output over earlier assumptions.
-- Before final response, check changed files and verification output.
+- **`todo`** — for any non-trivial task, create a todo up front (one item per concrete step). Mark `in_progress`/`done` as you go; `done` requires a `validation` note (how you verified it) — the structural form of "never claim done without verification".
+- **`scratchpad`** — working memory for facts found mid-task (file paths, errors, decisions). Use sections: `goal` (objective in one line), `findings`, `errors`, `artifacts`. Read `scratchpad` before your final report.
+- **Sub-agent handoff** — before `spawn_agent`, write what the sub-agent needs (files, snippets, how to verify) into the `context_transfer` scratchpad section; it's injected into the sub-agent automatically. The sub-agent does NOT inherit your short-term memory.
+- **`schedule_recall`** — when a task may hit the iteration limit, or has a wait/poll cycle (build, deploy, log watch), schedule a recall with a self-instruction naming specific tools/files (future-you has the tools, not your memory). Use `immediate` to continue after the limit or offload heavy work headlessly; chain recalls for multi-phase work. Only one pending recall per session — `manage_recall cancel` before a new one.
+- **`reflect`** — before a genuinely complex plan or when stuck (repeated tool failures), call `reflect` to surface assumptions/gaps. It costs 3 LLM calls — use selectively, not on routine edits.
+- **`memory`** — global cross-project facts (prefs, environment); not a substitute for `scratchpad` (session) or `docs/`/`NAVI.md` (project).
+
+On long tasks: the objective lives in `todo` + `scratchpad` `goal` (re-anchored automatically every few iterations); re-read the latest user request, trust verified tool output over earlier assumptions, and when stuck — `reflect` or replan instead of repeating the same failing call.
